lib:Cabal 220.127.116.11 can be build with GHC 8.8.1 as is evidenced by
it's just the executable exe:cabal 18.104.22.168 that can't be build with GHC
8.8.1; It can however be built with GHC 7.10.3 through GHC 8.6.5 as
However, exe:cabal 22.214.171.124 among other things is planned to be buildable
also with GHC 8.8.1
But it's perfectly fine to use an exe:cabal built with a different GHC than
the one you want to use it with; in fact exe:cabal supports being used with
all GHCs going back to GHC 7.0 (even though you can't build exe:cabal with
GHC 7.0 anymore)

Indeed, the main reason is that some of its dependencies weren't
GHC-8.8.1-compatible yet at the time its release. So we didn't yet bother
to update the bootstrap script yet.
What operating system are you on? is it possible for you to use one of the
binaries from http://downloads.haskell.org/~cabal/cabal-install-188.8.131.52/ in
